Bryan,
This guy is VERY lucky!!.
I read about this accident in the paper and while these accidents happen infrequently, it is still an accident, although one that could and should be made avoidable.
You would think that for a Line Mechanic, to be working at voltages like this and recieve a Hand-to-Hand shock, begs the question of How on earth did this occur?.
And also, we have very clear-cut regulations over here, for this type of work
and the need for cover-up gear and insulating gloves+gauntlets, I would be very interested in the results of the investigation by OSH.
